Inlays and onlays (partial crowns) in London

What are inlays, onlays and partial crowns?

Inlays and onlays are precision-made restorations crafted in a dental laboratory to repair teeth affected by decay, wear or fractures. An inlay fits neatly within the chewing surface of a tooth, while an onlay or partial crown extends over one or more cusps, protecting a larger area. They are custom-made from porcelain or ceramic and bonded to the tooth, giving exceptional strength and a natural appearance. Unlike a full crown, which covers the entire tooth, partial crowns preserve as much healthy enamel and dentine as possible, a cornerstone of tooth preservation and cosmetic dentistry.

The benefits of inlays and partial crowns

Choosing inlays or onlays offers a balance between aesthetics, function and conservation. They preserve more of the tooth than a full crown, and ceramic and porcelain restorations can last 15 to 20 years with proper care. The ceramic mimics the translucency of your natural teeth, and the result is stronger than a traditional filling, making it ideal for molars and chewing surfaces. Each restoration is custom-designed to restore your bite precisely, and laboratory fabrication ensures accuracy and long-term stability.

Who is suitable for an inlay or partial crown?

You may be a candidate if you have moderate damage or decay that is too extensive for a filling but does not need a full crown, if you want to replace large or old metal crowns or amalgam fillings with something natural-looking, if you have undergone root canal treatment and need to restore the tooth, or if you want a restoration that matches the shade and shape of your other teeth. At your consultation your dentist will explain the key differences between the options and recommend the most suitable based on cost, extent of damage and your preferences.

Common materials used for partial crowns

Porcelain and Emax are highly aesthetic and durable, ideal for visible teeth. Gold offers exceptional longevity and precision, though it is less aesthetic. Metal-ceramic combines strength with a natural appearance, and composite resin is a cost-effective option for temporary restorations. Each material has its own benefits, and our team will guide you to the best choice for your clinical needs.

Inlays, onlays and full crowns: the key differences

An inlay sits within the tooth cusps and preserves the most tooth, suited to small and moderate cavities. An onlay or partial crown covers one or more cusps with high preservation, suited to large cavities or cracks. A full crown covers the entire tooth with moderate preservation, recommended for severely damaged or root-canal-treated teeth. Each plays a role in tooth preservation depending on the condition of the affected tooth, and our dentists will explain which option gives the best balance of protection and aesthetics.

What happens during treatment?

Your dentist begins by examining the affected tooth and explaining why the damage has occurred, discussing all suitable options and giving transparent information about costs and benefits. Under local anaesthetic, decayed or damaged tissue is removed and the cavity shaped using minimally invasive principles. A digital 3D scan captures the exact shape of your tooth and bite, and a temporary restoration may be placed to protect the tooth while your final one is crafted. Your custom inlay or partial crown is designed digitally and created by our expert technicians in porcelain or composite. After one to two weeks it is cemented in place using strong adhesive bonding, with a dental dam isolating the tooth for perfect bonding. You will then receive detailed aftercare instructions to maintain gum health and prevent future decay.
